SparkleMax™’s unique patented formula creates the appearance of brighter teeth. By combining light refraction technology with a unique whitening agent, SparkleMax™ allows the user with stained teeth to achieve an immediate appearance of a brighter smile. As the hydrogen peroxide in the gel is broken down, oxygen acts upon the organic deposits on your teeth and oxidizes them into a lighter color. This process makes the overall tooth color closer to the natural unstained tooth color. The structure of the tooth itself remains unchanged. Each pen contains a 30 day supply. Apply up to three times per day.

cakedoo says.. I have been using SparkleMax for just over a week and doing as the directions say.. paint on 3x a day.. I have super sensitive teeth so most whitening products make my teeth feel like they are going to fall out.. I mean if I breathe in they hurt... I am thrilled to have found a solution, SPARKLEMAX!! it's so easy to apply, seriously, twist and paint on.. I can paint just on the my tooth surface and let it do it's job.. I apply in the am after brushing then mid day usually after lunch because I can brush at work then in the evening after brushing again.. I am telling you that this isn't like going in for a zoom treatment but I am seeing a difference in the color tone a little brighter and a little whiter.. OMG, I am love with SparkleMax.. I have no sensitivity, I am telling you nothing at all so if I can use, then the most sensitive person can use.. it's not messy either, I have had no dripping or oozing at all. The brush distributes a nice thin layer.. I get a little bit of a cooling sensation after I apply, it's hard to describe, but it's pleasant and not painful.. Now the best part it that is only costs.. $17.95!! WOW, now that is a deal for a month's supply.. I have a feeling you are going to start hearing a lot more about SparkleMax!

METSV says:  So this hasn't left my pocketbook since I got it a couple of weeks ago....perfect for teeth brightening on the go!  Like Denise, my teeth are usually pretty sensitive....even the strips you can buy at the store gave me achy-teeth and gums...but with SparkleMax I'm not getting any sensitivity at all...nope...just brighter looking teeth.    I love how the click up pen alleviates any mess and waste - I just click and apply to my teeth.... This is great if i have the occasional cup of coffee during the day - instantly takes care of any staining and dullness my teeth might have.   If I'm going out right from the office, I do a quick brush and then apply for nice bright teeth and a refreshed feeling.  I don't always use 3x a day, truth be told, yet I still see results.     I'll be clicking to the last drop!
